ADHESIVE-PLASTER SPOOL.

Specification of Letters Patent.

Patented Oct. 13, 1914.

T 0 all whom it may concern:

Be it known that I, Penn: S. BAUER, a citizen of the United States, residin at Chicago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Adhesive- Plaster Spools, of which the following is a specification.

My invention relates to spools and articularlv to spools which are intende to hold adhesive plaster tape and other similar material and has for one of its principal objects the provision of a novel and improved cutter for cutting off the required length of material which has been unwound from the spool.

The invention will be better understood from the followin description when considered in connection with the accompanying drawing illustrating a preferred embodiment thereof.

On the drawing: Figure 1 is a perspective view of a spool embodying my invention, showing a roll of adhesive plaster tape carried thereby from which a large part of material has been removed Fig. 2 is a sectional view taken at right angles to the axis of the s 001, and Fig. 8 is a sectional view taken a ong the central axis of the spool.

From the drawings it will be observed that the spool comprises a central core 5 and end walls 6 having erforations 7 at their centers through which the ends 8 of the core 5 are disposed and turned up against the walls 6 to secure the end walls in place. The end walls 6 are substantially flat and of circular form and when secured in osition are arranged in substantially para lel relation and are spaced apart a suilicient distance to permit a strip of adhesive tape 9 to be wound on the spool between said ends. It will be obvious that the length of the s 001 may be varied to accommodate strips 0 material of any desired width. Each end wall is offset ad acent its edge at 10 to provide a shoulder 11 and is bent upwardly beyond said shoulder at 12 and back upon itself at 13 to provide with the shoulder a groove extending intothe inner faces of the end walls and outwardly from the central axis of the spool behind the bent-back'portion 13. A

cutter 14 curved transversely to conform to the curvature of this groove and of length suilicient to permit its curved edges 15 to extend beyond the shoulders 11 is positioned in these grooves. The curved edges 15 are preferably bent upwardly and engage in the portions of the grooves behind the bentback portions 13 of the end walls so that these curved edges of the cutter cooperate with the bent-back )ortions and the shoulders of the end walls to interlockingly and slidably connect the cutter and the spool. One straight edge of the cutter is sharpened to permit it to readily cut the bandage, it being formed in the present instance of a plurality of serrations 16 as shown in Fig. l.

he cutter, as will be readily understood, slides freely around the periphery of the spool, so that it will not interfere with the tape either during the winding or unwinding of the spool. When it is desired to use a piece of the wound-up tape the required length is unwound from the spool. Then with the thumb of the hand holding the spool pressed upon the u per face of the cutter to hold it immovab e the tape may be readily and easily severed by pulling the unwound portion against the teeth 16. In the present instance the s 001 9 is shown as partially exhausted, it being understood, of

course, that the spool may carry a roll of tape of radius equal substantially to the distance between the central axis of the spool and the inner face of the cutter.

It will be apparent that the form of the container and of the cutter and their arrangement may be varied without departing from the spirit and scope of the invention and without sacrificing any of its material advantages, the form hereinbefore described being merely a preferred embodiment thereof.

I claim:

1. The combination of a spool having a circular groove formed in the inner face of each end wall extending about the entire periphery of said walls, and a cutter slidably engaging in said grooves, whereby the cutter may be moved about the entire pe riphery of the spool.

2. The combination of a spool having circular end walls bent outwardly adjacent their edges to form circular shoulders and gaged with said end walls and movable upwardly and back upon themselves beyond about the entire periphery of the spool. said shoulders, and a cutter resting in said PERRY s. BAUER. shoulders and having its edges bent up and 5 disposed between the upwardly and bent Witnesses:

back portions of said end walls, whereby A. WAKEFIEID,

said cutter is slidably and interloclringly en- F. E. CARD.
